Malthus wasn't wrong in a sense that /if/ there's geometric population growth, there /will/ come a point where a die-off of said population is inevitable.

Funny thing is that Malthus already recognized the effects that artificial birth control can have on the reproductive rate and was worried about that - I don't the the citation at hand though.

I agree that the birth rate outside Sub-Saharan Africa is probably too low and I think that this will become an issue, probably first in China, then the EU and finally in the USA.

Well, Malthus was right in terms of history, he just made one of the worst future predictions ever - he wrote his theory about human population crises right when it stopped being true.

I think we are seeing people having fewer children because they're depressed about the world/future expectations, of course, but that's not quite the same thing.
